Formation of the peat bog

Sedges (or carex) grow and help stabilise the soil. Later, sphagnum peat moss takes over and forms a dense carpet. These are species of moss that grow continuously and that provide an accumulation of organic matter on which sphagnum peat moss is able to grow. The vegetation becomes compact and creates the black and fibrous bogs resembling garden compost. However, this phenomenon is painfully slow and it takes thousands of years for a peat bog to reach a height of just a few metres.
